JOHN P. LANCASTER, OF GOSHEN, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 298,214, dated May 6,1884.

Application filed March 25, 1884. (No model.)

To all whom it may concern Be it known that I, JOHN P. LANCASTER, acitizen of the United States, and a resident of Goshen, in the county ofElkhart and State of Indiana, have invented certain new and usefulImprovements inOar-Couplings; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure 1 isa side view of myimproved carcoupling. Fig. 2 is a longitudinal vertical section. Fig. 3is a top view. Fig. 4 isaperspective view of the angular fastening forthe coupling-pin, and Fig. 5 is a similar view of the coupling-pin.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to automatic oarcouplings; and it contemplatescertain improvements upon the coupling for which Letters Patent No.271,085 were granted to me on the 23d day of January, 1883; and itconsists to that end in the improved construction and combination ofparts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicatesthe draw-head, whichis provided with a recess, B, for the entrance of the link 0, which isof the usual construction. The upper side of the draw-head forms atransverse bearing, D, opening inclined upwardly and forwardly, twolips, E E, forming the upper side of the bearing. The transverse upperyoke or bar, F, of the coupling-pin G rocks in this bearing, beingcapable of being slid out through the inclined opening of the bearing,and for the purpose of retaining the yoke in the bearing an angularfastening-plate, H, is secured upon a pin, I, passing through theangular fasten'ingplate and through the lips, and the inner end of thesaid angular plate forms a circular enlargement, J, which fits in acorrespondingly-shaped recess, K, formed between the inner edges of thelips. The yoke of the coupling-pin is provided with two pending arms, L,at its ends, which arms bear with their inner sides against the sides ofthe draw-head, and are provided at their I lower ends with chains orcords M, by means of which the arms may be tilted rearward in the samemanner as in my former patent. The pin is of the same shape as in myformer patent, with the exception of the lower forward corner, N,whichis cut off obliquely, and bears against the inclined inner side, 0, ofthe lower lip, P, of the recess in the draw-head, the oblique corner ofthe pin bearing against the inclined lip serving to force the pinslightly upward when strain is applied to the pin, re-

lieving the yoke of the pinfrom strain. The roof Q of the recess in thedraw-head is inclined toward its outer end, the inner end of the recessis provided with a transverse lip, R, slightly above the center of themouth of the recess, and the bottom of the recess is concave, as shownat S, and in Fig. 20f the drawings is shown in dotted lines thepositions of the coupling-link, either resting with its inner .endagainst the inclined roof of the recess,

lowering its outer end for the purpose of coupling with a draw-headlocated below its level, or restingwith its inner endagainst the underside of the transverse lip, allowing it to conple with a draw-head atits own level, or resting with its middle upon the lower lip of themouth of the recess, and with its inner end against the concave bottomof the recess, for the purpose'of coupling with a draw-head at a levelabove its level.

It will be seen that by removing the angular fastening-plate the pin maybe removed, when the draw-head may be used with a common coupling -pin,which may be inserted through the circular recess between the lips atthe upper side of the bearing, in case of an accident to the T-shapedcoupling-pin.

Having thus described my invention, 1 claim and desire to secure byLetters Patent of the United States--- 1. The combination of thedraw-head forming a transverse bearing upon its upper side, and havingthe inner side of the lower lip of its recess inclined, ,with theT-shaped coupling-pin rocking with its yoke in the bearing upon theupper side, and bearing with its obliquely cut-off lower forward corneragainst the inclined inner side of the lower lip of the recess, as andfor the purpose shown and set forth. Y

2. The draw-head having theroof of its re- IOO cess inclined toward theforward end, having a transverse lip in its rear end slightly above themiddle of the mouth of the recess, and having its bottom concaved, asand for the purpose shown and set forth.

3. The combination of the draw-head forming the transverse bearing atits upper forward corner, having the upper lips forming a circularrecess or bore between them, the T-shaped coupling-pin rocking with itsyoke in the bear ing, and the angular fastening-platesecured upon a pinbetween the lips of the bearing,

and having its inner end forming a circular enlargement fitting into thecircular recess between the lips of the bearing, as and for the purposeshown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixcd my signature in presence of two witnesses.

JOHN P. LANCASTER.
